loadlngcan coolers, or more'particularly` .toa machine for receiving cans as theyilare carried byr a conveyororfthe like, counting themand arranging them in rows ,of predetermined numbers, andthen depositing them in a container.

-It is customary in the canning oil-fish and other.l foods to subject the liilledandusealed cans to a cooking temperature and thereafter to., subject the cans to .the` atmosphere fory cooling before they are labeled and packed into boxesor cartons for shipping. To facilitate handling ofthe cans before theyfare cooked and also *during*y their cooling, they are placed in large metal'ilats or baskets, known as can coolers, .in which they re-v main until they are cooled and transportedato the labeling machine. Y It is the object of the presentinvention yto rprovide a. machine for receivingv cansv fromA a conveyor, which mayk deliver thern'from a seamer or'the like, and for depositing them compactly and efllciently in a cooler entirely automatically.

The elevator also has a movement from side to side rduring its descent and'ascent so thatwalternate rows of cans are staggered to enable the placing of a maximum numbervof cans in a Cooler of 4'a given sizes. r A

`The conveyor-I0 is unconventionalconstruction, and consists "of av belt or metallic conveyor comprising'chain links, each 'carrying a small metal plate to form-a levelsurface for supporting the cans on top of its upper'flight. vThe Vpath of this conveyor is indicated by the'broken line.

f l 6 in Fig. 2. It iscontinuously driven, by a motor which operates all of themoving' parts ofthe machine; througha series of chains and sprockets indicated at I-'l land l8;`tlie'chain*l8lbeing driven byv a spro'cketwhich' isflxed to'an'idlerpulley' l 9 driven by a-'belt '20 leading over a motor pulley 2|' constantly driven b'y the motor illustrated at'ZZinFiglLL' yThedetails of nconstruction of 'the turret Il i are m'ost'clea'riy"illustrated in Figs. 2, 4 and 5.

The turret includes a head 25 supported by averliver them on to the conveyor I2. In order that the turret head 25 may be accurately timed with the operation of the elevatorand other parts of the machine which are driven by the same power source, the head is clamped by means of bolts*y 2l and an annulus 30 to a separate hub portion 3|, which in tum is keyed or splined to the rotatable shaft 26. This shaft passes through a bed plate v32 suitably supported by the frame-,-

work of the machine and is journaled adjacent its lower end in a bracket 3l. 'A bevel gear 35 l at the lower end of the shaft is driven by a similar gear 36 on a stub shaft 31 connected by sprockets and a chain 38 to a main shaft 39..

The main shaft'39 is driven through'a chain 40,

shown in Fig. 1, and trained over a sprocket on chine through the -medium/v ofraclutch /ll eon-v f.

trolled by an operatingff'lever 46, as shown in Figs. land 2,.

When the clutch ,is engaged, the entire ma,-

r/chine is operating and the turret head 25 rotates continuously. As.y the can coolers being loaded are of a width just to receive twelve cans, the recesses 21 in the turret head are twelve Yin number, and when twelve cans have been recans on the conveyor I0 and prevents delivery yof cans to the machine'for a brief period of time during disposal of the cans last counted. ylis.

roller 51 which is engaged by a rise 56 on the periphery of a circular cam '59. The cam 59 is mounted on the upper end of a shaft 60, which shaft, as shown in Fig. 2, carries a lbevel gear 6I at its lower end in mesh with a bevel gear 62 on the .end of a stub shaft 63, vwhich is driven by a chain 64,., and suitable sprockets from the stub shaft 31. The shaft 60 which carries and rotates the cam 59, operates at half the speed of the turret, and` the cam is timed to close the gate lover the twelfth recess Vfor every other rotation of the turret. The gate 50 is also em'- lployed as a safety stop to prevent the feeding of cans to the turret whenever there is no cooler presentbeneath the elevator to receive the cans. To hold the gate closed a pawl shown at 65 in Fig. 4 is urged by a spring 66 against a stop 66a to engage -the pin which supports the roller 51 at theendfof the bell crank 54 and hold the. bell crank in its gate closing position. f This pawl is carried `atthe upper endo'f a'vertical shaft 61, and fixed to thel lower end of this/shaft is an arm 68 having an end which normally projects into the/path of the coolers/as theyare conveyed beneath the elevatorfrohi which they receive the cans. vThe presence of a coolerfbeheath the elevator urges/)the arm ,lieto'um/p0 sition illustrated 'in Fig.` 4, thug turning the shaft 61 slightly and holding the pawl 6.5; against the tensione! theV spring 66 in a .position where it will not engage'and retain the leyer 54m its gate closing position.- If, however; no cooler is f presentv beneath the` elevator the end of the arm pin ontheleveril will snap into place thel ilrst 'time that .ther lever is operated to'close the gate by the rise 58 on the cam 59. .v As this would In order that. the turret head will count eleven 4 cansv rather than twelve on every-second rotation, a gate is provided'for closing the twelfth recess 21 in the turret head. `This gate is shown at in Fig. 4, and consists of anfarcuate strap disposed substantially parallel with the periphery of the turret head and having one end curled about and pivotally supported byya pin 5| which depends from a 1ever.52 which/is mountedfor swinging movement about the center of rotation of the turretby having its inner endembracing the turret head 3l, as shown in Figs. 4 and 5. A tension spring 52a engaging the lever 52 urges the gate toward its open position. The free end of gate'50 is slidable in ia groove 53 formed in l the periphery of the turret headl and intercepting the points between the recesses 21, as shown in Fig. 5, so as to form a continuous recess` which receives the gate during rotation vof the turret. On alternate rotations of the turret thelever 52 is swung to the dotted line position indicated in Fig. 4 toadvance the free end of the gate 50 across the path of the cans entering the turret from the conveyor I 0, thusclosing the twelfth recess 21 and intercepting the can` which would have entered that recess and causingthe turret to delivel` eleven cans to the conveyor I2 rather than twelve. This closing of the gate -is accomplished by a bell crank 54 pivoted on pin 55. One end of this bell crank is connected by a pin and slot connection 56 with the lever 52, and its opposite end carries an anti-friction take place normally only after the delivery of eleven cans `to vthe turret and the safety lock would thus fail to operate on alternate rotations of theturret, `a second rise 69 is provided onthe cam 59 for'closing thegate, but as this rise yis smaller in width than the rise 5B it closes the gate -only after the twelfth can has been received andl for no purpose other than to present the arm 54 to the pawl v65.v in the event that there is no cooler in position to receive the cans.

The conveyor I2, which is of conventional construction and consists of chain links each carrying a rectangular metallic plate is trained over a drivelsprocket 10, as shown .in dotted lines in as shown in Fig. l3. In order to prevent the lower flight of this conveyor from sagging and thus interfering with other mechanisms, the entire conveyor wherevit crosses in front of the' elevator is housed, as shown inFlg. '1, by two pairs of angle irons bolted together to form inwardly projecting top ledges 12 supporting the platesof the upper night of the conveyor and bottom ledges 13 supporting the plates of `the lower flight of the conveyor, the conveyor plates being shown at 14 and the chain links to which lthey are secured at 15. vThe conveyor driving sprocket 1li is keyed toa shaft on the inner end lof Ywhich is fixed a bevel pinion 16, which, as shown in dotted lines in Fig. 4, meshes with a bevel gear 11 (see also Fig. 5) keyed tothe shaft which supports and rotates the turret head so that the conveyor is driven .constantly when the turret is in operation. The

cans received by the conveyor l2 Vare stopped by a plate 18 extending across the conveyor, as shown in Fig. l, in positions opposite the chutes by which they are to be received in the elevator I3.A The pusher bar Il, which is provided with arcuate recesses 1'! to register with and assist in guiding the cans into their respective chutes, is then adt yanced overthe conveyor to-slide thecans off "ofit and into the elevator. This pusher bar has a pair of forwardly extending brackets 30, the outer ends of which are pivoted to the upperends of` a pair of/levers 8| mountedon fulcrumpins I2 andpivotally connected at their lowerv ends withial bar 83 which extends transversely of the machine and connects the two levers together for simultaneous movement. Adjacentfthe centerof.

this bar a connecting rod. 84, extends rearwardly and has a bifurcated end'85 (see Figs3 and 5) which embraces `the main shaft 39` vbetween a collar 86 and a boxfcam 81 Apin,88f(shown in dotted lines in Fig. 5)` projects into the cam so that upon rotationof the shaftthe :connecting rod uis reciprocated to swing theJ-leversyl to advance andfretract the pusher'bar, the boxl cam /31 being contoured to time the operationof vthe pusher` bar with relation to the operation of the 'turret which 'feeds' the `cans toward their position in front of the elevator. i

The individun hoppers ci theeievatcr by'whicn the cans' are `received are effectively closed at their lo/wer ends by two groups of elements presently to be described, each group being supported on one of a pair of parallel shaftsliand 9| (see Figs. 2, 4 and 7) which, as brest illustrated'v in Figs.f2 and; 5,

tending between thesel members I ||l and supported by them are a back wall 'I I l and 'a' front wall I2, and the back wall carriesja; plurality of par-` titions I|'I,3 which extend tqwardethe front wall,

terminating y.just short ofy it',4 "and fdepend downwardly,4 terminatingl at their' lower extremities in tapered endssuch,as shown at 'I'Iiiri Fig. 8."v

Asill |I5,"as illusn trated in Fig. 8,' spans .the space between'vthef' conyey'or andthe hopper and overlies the upper edge of the wall .I'| 2 to facilitate deposit of the cansin ,the hopper. The bottomof ythe hopper is' effectively closed by fingers ||6 and I|1v'"s uplported i in rows on tively,^to which they arel keyed and also secured against longitudinal imovement'by a set screw eitherv to the' closed position rillustrated in'Fig. 8.

` or swung from that position to a vertical `or open position wherein the canob'structed by themy isl permitted/to gravitate to the cooler by which'it vvis receiv/ed below the elevator The fingers' IIB are journaled at their opposite `ends in castings 92which retain the shafts in spaced parallel rela-v tionship extending tramsverselyl of-ft-hemachine and which are mountedffo vertical sliding movementon posts '93"secured/i'n' vertically .aligned brackets and 95. The weight ofthe elevator iscounter-balanced byy springs 96,.-best/shown in Fig. 3, and it isiraised vv'and'loweredduring the operation of the machine by a connecting rod 91 pivoted to the casting 92 at its upper end by means of 'a pinf98 and connected at its lower end with However, as the rows of cansl in the can cooler areA staggered the elevator must on every .alternate descending movement, `shift sidewise. a distance I'|1k are,l however,` terminated considerably short` equal to half a can diameter and then uponi-ts ascent return to normall alignment for reception of cans.. This movement is accomplished by sliding the shafts 90 and 9| axially during vertical travel of the elevator. These shafts are embraced by a casting |0| (see Figs. 4 and 5) which has a ed to slide over a vertical post |03. The post |03 'is engaged and supported at its upper yand lower endsby identical levers |04, both fixed to a vertical-rotatable shaft |05 which at its lowermost end carries a lever |06 with a downwardlyprojecting pin or anti-friction roller |01 (seeFigs. 2 and 3)" jwhich extendsv into a peripherally grooved cam |08 which is mounted on and driven by ther shaft 63 and which is contoured and timed to effect sidewise shifting of the entireelevator during its descent and returned -to normal during its ascent on alternate operations.v 1

. The general assembly of the elevator I3 is best illustrated inF-igs. 1, 5 and 8wherein the castings |0I are shown each as supporting a vertically disposed, channel-shaped member I|0.v `Excentral vertical opening |02 embracing and adaptand i i1 are' positioned in alignment with the par,- 1 titions I|3 so that eachnger `projects partially intotwo of the reticules formed byl the partitions Fig. 6,"wherein each fingeris'illustrated ashav-A ing twocon-cav'eu sides formed on an arc^which is the same asthe peripheral contour of ltheizcan. Thus, four-'fingers serve to forma guide which accurately,positions'- the can'as it yslidesfdownak wardly toward thecooler. Both the fingers IIEV and |,1I are slotted, as indicated at"| Isand H9, respectively, y'to receive the edges of the dividing partitionsY I3 and to permit them-to swing over the tapered lower ends of these partitionsyas shown"l in Fig. ii.v When the elevator isy in its lowermost position, the lower-ends of the .fingers IIBstop just' abovev the bottom of thefcooler'in which the "cans are tobe deposited. The vfingers off' this point and each nger supports a curved plate |20 which maybe formed of thinvspring steel or the like, and which is contoured to register with thecans in the row preceding the row which isl being deposited. Consequently, when the upper row shown in Fig. isbeing placed in the coolerfand the kfingers 'I l1 swing from theire inclined position'to their vertical position to release `the cans, t'heplates'v |20 register with the cans in the row last deposited and urge thesef vcans forwardlyin the cooler to insure that they are perfectly aligned fand contacting :the `cans which precede them imorder 'to conserve space'. The mechanism foi",` openingy and` closing the rlingers IIB and I|`I is shown ,in- ',wherethe shafts and 9|, are illustratedasftted'with gear quadrants |2| yand |22,-'respectively,vwhich mesh with each other. The quadrant |122 carries a tail |23 whichl upon downward movement of the elevator contacts a stop in the form of an adjustable lset screw |24, which during ythe last part of the downward movement of the elevator effects just ,sufiicient rotation Voftheshafts to move the fingers to their vertical or open posi,- tions. An identical stop |25 contacts the tail, |23 during` thek upward movementvof the elevator, thus reversing the rotationvof the quadrants and the 'shafts 90 and 9|, respec-rk again returning the fingers to their closed or can-receiving positions.

The conveyor chains vI5, which support and advance the coolers, have their upper flightssupported and guided in channels |26, These chains are trainedy over sprockets |21 on a shaft |29 at one end of the machine and over sprockets |29 on a shaft |30 at' the opposite end of the/machine.' Feed bars I3| extend transversely of the two chains and are driven by lthem to engage and advance the coolers |32. The leading edge of the cooler is presented by the feed bar to a position'beneath the elevator to receive the first row of cans and the cooler is then advanced a distance equal to the width of a row of cans for each operation of the elevator until it is` filled, at`

which time the cooler conveyorchains I are advanced approximately twice this distance,

which is sufficient to bring the leading edge of' the next cooler into registry beneath the elevator for the reception of the next row of cans deposited. To feed the cans in this manner, the

' shaft |30 is provided with a toothed wheel |33 (see Figs. l and 9), by which it may be driven. A pin |34 resting on top of this wheel and adapted to engage with the teeth thereof, isvcarried by the end of arod |35, the opposite end of which carries an eccentric strap |36 which embraces an eccentric I 31 fixed to and rotated bythe main shaft 39.` The action of the eccentric upon each rotation of the shaft 39 causes the pin |34 to f' engage behind one of the teeth on the wheel |33 and advance the same a distance which effects the movement of the cooler feed the Width of one row of cans. As there are fourteen rows of cans in each cooler, the wheel |33 has fourteen teeth and one space, as indicated at |38, in which the pin 34 will be ineffective. When this space is reached a similar but smaller toothed wheel |39, which is also carried by the shaft |30, and which has a single tooth projecting from its periphery, is engaged by a pin !40 identical with the pin |34 and carried by a rod |4| identical with the rod |35,'and also driven by an eccentric |42on the main shaft 39'. Thus, rwhen the toothed wheel |33 has advanced the cooler fourteen spaces and becomes inoperative for the fifteenth space, the wheel |39 is timed to effect engagement of its single tooth with the pin |40. As the diameter of this wheel is about half that of the largerA one, the can-conveyor is advanced approximately twice the usual distance, which is sufiicient to bring the second cooler into position to receive its rst row of cans and also to advance the large toothed wheel |33 to a position where it will again operate to advance the cooler for the reception of the next thirteen rows of cans. As the coolers travel along the conveyors, one side is guided by the immovable rail |43, as shown in Fig. 1, while on the opposite side a shorter rail |44, which is urged inwardly by springs |45, insures perfect alignment of the cooler as it passes beneath the elevator.

While the present invention has for the purpose of illustration been disclosed in the form of` a machine constructed for the specific purpose of arranging cans in ar cooler, it is readily adaptable to other uses, and, in fact, for any use where cans or similarlyvshaped objects are to be arranged in orderly manner in any type of container or on any surface.
